The WiNRADiO WR-G31DDC 'EXCALIBUR' is a high-performance, low-cost, direct-sampling, software-defined, shortwave receiver with a frequency range from 9 kHz to 50 MHz. It includes a real-time 50 MHz-wide spectrum analyzer and 2 MHz-wide instantaneous bandwidth available for recording, demodulation and further digital processing
The receiver's superior performance results from its innovative, direct-sampling, digital down-converter architecture along with the use of leading-edge components and design concepts. These all result in a very high IP3, wide dynamic range, high sensitivity, and tuning accuracy. These key features create a receiver in a class of its own, with wide application potential, at a very affordable price. The receiver's robust front-end is equipped with an ultra-high-linearity amplifier which results in exceptional strong-signal performance. An advanced dithering technique eliminates spurious signals without significantly increasing the receiver's noise floor.
The superior 16-bit 100 MSPS analog-to-digital converter provides exceptional performance over an extremely wide range of signals. The entire 2 MHz DDC (digitally-down-converted) bandwidth is available for recording and demodulation.
Three demodulators allow the simultaneous reception of three signal frequencies within the 2 MHz bandwidth.
